Among Gijs Gieskes many mad creations, this artist has hacked the browser as well as hardware. (“Browser bending,” anyone?) With all the talk of browsers, he reminds us of this previous work, which combines hardware, server software, and browser software to make a MIDI sequencer for YouTube.

A arduino usb hid keyboard emulator is used to convert midi note messages to keypresses. This can be usefull to controle online videos with midi, in combination with the youtube mixer (uses the youtube javascript api).
